The modulus of elasticity of

steel is 3 times higher than of

aluminium.

For identical profile cross

sections the deflection of steel is

three times hi her than the

Larger spans can be achieved with

steel profiles by using the same

cross sections.

timber

Steel has a lower thermal extension

than aluminium!

Steel, glass, concrete have almost the same coefficient of extension, therefore no

extension profiles are required when using steel.

CO2 Emission at production*Aluminium 13 9 - 15 5 k

Substantially lower energy consumption during production of steel as compared

to that of aluminium.

No toxic product waste with steel production.
